Airstones DO increase available oxygen in the water, but not in the way most people think. The process is 2-fold. First bubbles rising from the bottom collect CO2 molecules. When they reach the surface and burst, the CO2 is released along with oxygen inside the bubble provided by the air pump (not from within the tank water). At this point a gas exchange is possible... CO2 out - new oxygen in.
But this can only occur if there is physical agitation on the water surface, which is the second part. A bursting bubble releases a tiny amount of energy which agitates the water molecules providing a tiny ripple. Hundreds of bubbles provide enough agitation to allow a gas exchange to occur (albeit a small one).
Beyond that, airstones do absolutely nothing apart from look really pretty and consume electricity from the air pump.
If ya really want to know more do a search on Co2 oxygen exchange process in H20.
Hope that helps clear that up!

It aerates the water (helps put oxygen back into it).
Since bettas are labyrinth fishes, they could probably care less about an airstone. They have an organ that allows them to breathe surface air as well as take oxygen from the water, so the airstone, while not hurting one at all, is unnecessary.

An airstone helps get more oxygen into the water.
A Betta is a labyrinth fish and needs to breathe oxygen from the surface. The stone will minimize his visits to the top, but not by much.

an airstone helps gas exchange in the aqaurium, the bubbles pick up co2 on there way out and disturb the surface tension of the water allowing oxygen to be absorbed easier.

If you are using an undergravel filter, burying the airstone in the gravel might interfere with the filtration system. Other than that, the bubble size really doesn't matter, as far as the oxygen. Whichever you prefer.

Airstones are for decoration only. They do not add dissolved oxygen to the water they just blow bubbles that float to the surface. Dissolved oxygen can only enter the water by means of movement of water against air. i.e. waves, filters, waterfalls, fountains etc.
Betta's may or maynot care one way or another for airstones. They aren't needed for oxygen but can have cool effects in a tank.
Either way it is up to you.

air stones supposedly aerate the water, but studies have shown it does little to help the level of oxygen in the water.
bettas breathe from the surface, so aerators aren't needed. actually they cause extra water movement which can stress bettas. instead of wasting your money on an air stone make sure you have a heater and preferably a filter for your betta :)

The air-stone disperses the air bubbles, making the bubbles smaller and it prevents the air from causing too much of a current inside the tank...therefore making it easy for the fish to navigate.
My Beta never complains about the air-stone in the tank.
It's fun to put the air-stone in one of your decorative pieces.

Unless you have real plants than it is for show.
